Pneumoperitoneum has been associated with a decreased flow in the superior mesenteric artery and portal venous system. Intestinal blood flow was studied during a 2-h pneumoperitoneum with carbon dioxide (CO2) or helium in a porcine model using colored microspheres. ⋯ Intestinal perfusion does not change significantly during prolonged pneumoperitoneum at a pressure of 15 mmHg with CO2 or helium.

The laparoscopic approach promises to become the gold standard for the transabdominal management of full-thickness rectal prolapse. The aim of this study was to review our experience and to highlight the functional results achieved with this new technique. ⋯ Laparoscopic rectopexy with or without resection is both safe and effective. Advantages include low-morbidity, improved cosmesis, the rapid return of intestinal function, early discharge from hospital, and a low recurrence rate. The fecal continence score is improved; however, constipation is frequently worsened.

Comparative Study
The impact of a laparoscopic colorectal surgeon on the laparoscopic colectomy experience of a single academic center.
The objective of this study was to evaluate the impact of a laparoscopic colorectal surgeon (LCRS) on the laparoscopic colectomy experience of a single academic center. ⋯ The addition of an LCRS had a significant impact on this center's experience with laparoscopic colectomies in terms of both volume and case complexity.

Randomized Controlled Trial Comparative Study
Preoperative and postoperative levels of interleukin-6 in patients with acute appendicitis: comparison between open and laparoscopic appendectomy.
Cytokine interleukin-6 (IL-6) is an early marker of systemic inflammatory response and tissue damage. This study aimed to evaluate the levels of IL-6 after open and laparoscopic appendectomy to compare the degree of surgical stress associated with these procedures. ⋯ The operative stress in open as compared with laparoscopic appendectomy is not reflected by circulating levels of IL-6.
